Venture loop on GitHub: trending repos -> pitches -> board -> build -> Pages

venture.py runs one stage per tick on a `venture` card: scout (GitHub search,
repos with the most new stars this week), pitch (each seat proposes one static
page product), board (Borda over seat rankings), build (the Venice worker on
gh-pages), ship (GitHub Pages). TIME_VENTURE=on starts it; off by default.
